Answer:

x = 10√3

Step-by-step explanation:

Because of the right angles, we can use Pythagoras

30² - x² = y² (a) Largest triangle

y² - 20² = h² (b) Medium triangle

substitute y² from (a) into (b)

30² - x² - 20² = h²

500 - x² = h² (d)

x² - h² = (30 - 20)² (c) smallest triangle

substitute h² from (d) into (c)

x² - (500 - x²) = 100

2x² = 600

x² = 300

x = 10√3

Before the celebration for

Minchanka [31]

Answer:

$1,165\frac{1}{3}\ yd$

Step-by-step explanation:

In this problem we have a regular octagonal barrier (That means that all the length side are equal)

Find out the perimeter of the barrier

The perimeter is equal to

$P=8b$

where

b is the length side of the barrier

we have

$b=145\frac{2}{3}\ yd= 145+\frac{2}{3}=\frac{437}{3}\ yd$

substitute in the formula of perimeter

$P=8(\frac{437}{3})=\frac{3,496}{3}\ yd$

Convert to mixed number

$\frac{3,496}{3}\ yd=\frac{3,495}{3}+\frac{1}{3}=1,165\frac{1}{3}\ yd$

Answer:

The length of the shortest side on the blueprint is 10 centimeters.

Step-by-step explanation:

Given:

George is an landscape architect and is designing his backyard in a blueprint. In the yard, he wants a garden in the shape of a triangle. The length of the longest side of the garden will be 600 centimeters, and the length of the shortest side of the garden will be 400 centimeters. If the length of the garden's longest side on the blueprint is 15 centimeters.

Now, to find the length of the shortest side on the blueprint by using an equation.

Let the length of the shortest side on the blueprint be $x.$
